Reform UK's cumulative councillor departures reached roughly 40 by 2 July on the tracker kept by Liberal Democrat peer and elections analyst Mark Pack 1. The pace has slowed sharply from the 22 lost in the fortnight after May's elections . The figure counts resignations, defections and expulsions since the May local elections, and the deceleration matters because a party that tripled its councillor base needs to hold those seats to run the councils it won. A separate tracker citing nearly 100 departures blends different cycles and is not comparable.

Reform UK's cumulative councillor departures reached roughly 40 by early July on Mark Pack's tracker, a marked slowdown from the 22 lost in the fortnight after May's elections.

Key takeaway
Reform's councillor losses have slowed to roughly 40 since May, easing fears of a structural collapse.
Deep Analysis
In plain English
Reform UK won a large number of council seats in England's May 2026 local elections. Since then, some of those councillors have quit, been suspended, defected to other parties, or resigned. Mark Pack, a Liberal Democrat peer who tracks these numbers, counted roughly 40 cumulative departures by 2 July. That is a much slower pace than the 22 lost in just the first fortnight after the election. This pattern, a fast wave of losses followed by a slowdown, also happened to UKIP after its own council surge a decade ago, as parties expanding quickly tend to lose their weakest recruits first.
Root Causes
Rapid attrition after a surge election typically front-loads onto candidates who were selected quickly and with limited vetting, the fastest and easiest departures to identify and remove or who resign first.
Once that initial cohort has left, the remaining councillors are disproportionately those who survived early scrutiny, which is the structural reason the departure rate slows over time even if underlying discipline problems persist.

Reform's councillor losses start to slow
The bleed of Reform councillors is easing, suggesting the post-election churn was a spike rather than a structural collapse of its local base.
Different Perspectives
Democratic Unionist Party
Gavin Robinson rejects Sinn Féin's characterisation of the institutions as precarious, says the DUP is "committed to" delivering for the public, and will not be "goaded" into a dispute he attributes to Treasury funding rather than unionist bad faith.
Sinn Féin
Conor Murphy says Stormont power-sharing is in "a precarious place" and blames the DUP for lacking "the political will to make it work", while insisting his own party remains "wedded to power-sharing".
Council leaders in West Sussex and Cambridgeshire and Peterborough
Officers must recruit staff and set shadow budgets through the autumn for boundaries Whitehall has not yet drawn, after October's deferral cost three months of planning time without settling anything, while their May 2027 election date has not moved.
Restore Britain
Restore Britain beat the Conservatives into fifth place in its first mayoral attempt, evidence Rupert Lowe's party has already displaced the Tories as the default home for voters leaving the Conservative column on Reform's right flank.
Scottish National Party
The SNP, through deputy leader Keith Brown, calls Sarwar's peerage exit "the most undemocratic trick in the Westminster book", arguing Scottish Labour now runs on a caretaker leader chosen by patronage rather than by Scottish voters.
Conservative Party
The Conservatives finished fifth in Greater Manchester, beaten by Restore Britain, a party founded this year, in a contest the Tories once treated as a two-horse race against Labour.
